I have applied for federal skill worker program express entry on 14th april 2018. I have not received a single update or reply from ircc since last 19 months. My medical examination validity has been expired on 10th march 2019. I have applied for CAIPS notes two times. Both the times I have received same query which is already been solved. Total 19 months has been completed. I have sent repeated attempts of enquiry through emails and web form case specific enquires and fax. Yet no reply from ircc. What shall i do now?
